严重: Exception starting filter struts2

Answer 1

web.xml
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Answer 2

首先配 WEB.XML  然后还要 配 STRUTS.XML   

Answer 3

web.xml,我一般这么配置
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>
  org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
  </filter-class>
  </filter>
 
  <filter>
<filter-name>strutsFilterDispatcher</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
  
  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>*.action</url-pattern>
  </filter-mapping>
   
  <filter-mapping>
<filter-name>strutsFilterDispatcher</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>然后struts.xml中还要做一些配置来控制页面的跳转等。

在web.xml配置
<filter>
        <filter-name>struts2</filter-name>
        <!-- struts 2.1.6以下版本用org.apache.struts2.dispatcher.FilterDispatcher-->
        <!-- struts 2.1.6以上版本用org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter -->
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
   </filter-mapping>struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 默认的视图主题 -->
    <constant name="struts.ui.theme" value="simple" />
    <!-- 把struts2的Action对象工厂 交给spring的对象工厂来创建Action -->
    <constant name="struts.objectFactory" value="spring" />
    
  <package name="login" namespace="/login" extends="struts-default">
<action name="login" class="loginAction">
<result name="main">/jpf/root/main.jsp</result>
<result name="index">/login.jsp</result>
</action>
    </package>
</struts>
